We registered the reports of the participants using semi-structured interviews while they were working at the markets or when they were in the water to interact with river dolphins. We registered dolphins and human behavior using the ad libitum method. Most of the children interacting with botos were boys - we observed only two girls swimming with the dolphins. All the fish species offered to river dolphins are commercial. Tourists were often involved in interactions in the Santarém region, but not as frequently in the city of Mocajuba. Nevertheless, in both places human populations were aware of the interactions of children/adolescents with botos. The interviewees did not show fear of botos, as is common in other localities of Pará State. Although some of them attributed mystical powers to those animals. The children demonstrated to know about river dolphins behavior and morphology, as well as the occurrence of other species of aquatic mammals in the surrounding areas. Despite the diversity of aquatic mammals in those areas, we noticed that the knowledge of children regarded mainly botos and tucuxis (another river dolphin species), probably because these are the most conspicuous aquatic mammal species in the region. Furthermore, according to the reports of the interviewees these interactions between dolphins and humans have been going on for a long time in both areas, more than 30 years. The presence of newborn calves along our field observations indicate that this behavior may be passed down through generations of botos. In short, our results expand the knowledge regarding interactions between humans and Inia sp. in the Amazon. Moreover, it is essential to intensify the systematic research effort in order to evaluate effects of direct interaction activities on river dolphins and humans alike. In addition, educational measures in Eastern Amazon may promote realistic and efficient plans for the conservation of this species. Keywords: interactions, river dolphin, Amazon. 2 1. Introduction The evolutionary history of humankind was founded on experiences with other species considering both biological and cultural aspects of these interactions. The explanations for such relationships established between humans and other animal species may be found in the biophilia hypothesis by Wilson (1984), which states the existence of an innate emotional bond between human beings and other life forms (Manfredo, 2008). Also, biophilia is the fundamental interdisciplinary field to investigate those interactions (Kahn Jr, 1997). According to Descola (1998), there is a variation in the sympathy and attitudes towards animals according to cultural traditions. In this context, cetaceans have caught human attention for a long time, and some cultures, as in Greek mythology, those animals are seen as deities (Pantidou, 2014). Some authors point out that the sentiments and beliefs of humans regarding cetaceans are sufficient for considering the welfare of those species important (Barstow, 1991; Scheffer, 1991). The curiosity of men about cetaceans led to the confinement of various species in captivity. There are even some reports of an orca (Orcinus orca) in an enclosure made of nets while being attacked by soldiers armed with spears in Ancient Rome, and records of harbor porpoises (Phocaena phocaena) put into tanks of a privet collection in France during the 1400’s (Collet & Duguy, 1987). Furthermore, in recent years the frequency of direct interactions between humans and cetaceans has been increasing considerably due the larger amount of fisheries and tourism activities as dolphin and whale watching, and swimming with these animals (Lusseau, 2003; Lusseau & Bejder, 2007; Reeves et al., 2003; Samuels et al., 2000). Considering this increasing amount of interaction records between humans and cetaceans, our study focuses on interactions between humans and botos (Inia sp., Blainville, 1817), which are the largest of river dolphins and occur throughout the Amazon, Tocantins, Guamá and Orinoco river basins (Best & da Silva, 1989; Da Silva et al., 2008; Hrbek et al., 2014; Santos et al. 2012, 2014). The behavior of these dolphins towards humans varies from shy to curious and even though some local communities and tourists consider the species charismatic, the relationship between botos and humans are not always harmonious. In the case of fisheries, the damage dolphins inflict to the nets cause losses and negative reaction by fishermen (Iriarte & Marmontel, 2011; 2013). In the Amazon, interactions between dolphins 3 and men usually occur in fisheries (Iriarte & Marmontel, 2011; 2013) and social-cultural contexts in the case of legends and the commerce of byproducts of botos (Alves et al., 2010; Alves e Rosa, 2008), as well as in situations that attract tourism (Romagnoli, 2009; Alves et al., 2011; Alves et al., 2011). According to Alves and colleagues (2012), botos (Inia geoffrensis) demonstrate a tolerant behavior towards activities involving humans and therefore tend to get closer often and to interact more with people. On the other hand, Aliaga-Rossel and his colleagues (2006) report that areas with high human activity may disrupt the grouping behavior of Inia boliviensis. In Central Amazon, interactions between botos (Inia geoffrensis) and tourists became popular in riverside communities of Amazonas State, and have been catching increasing attention of local and international media, attracting thousands of Brazilians and foreign tourists interested in feeding and swimming with these animals (Romagnoli et al., 2011; Alves et al., 2012). Several studies describe the risks of interactions in which tourists swim with cetaceans (Constantine, 2001; Samuels & Bejder 2004; Romagnoli et al., 2011). Moreover, other studies also demonstrated that unplanned tourism increases the levels of stress hormones in disturbed animals and may induce physiological changes and alterations in the blood biochemistry (UNEP, 2006). In addition, Alves and colleagues (2012) reported that when populations of botos are conditioned with food these dolphins might become aggressive towards each other and humans. Other risks to the animals include changes in behavioral patterns, health, and the dependence on induced feeding, in addition to the harm by tourists during the interactions (Orams et al., 1996; Orams, 2002; Alves et al., 2011). In Eastern Amazon, more specifically in Pará State, Brazil, the influence of legends and myths related to river dolphins may lead children and teenagers to avoid such species, harmonious interactions are rare and hitherto not reported for this region (Rodrigues et al., 2012). Therefore, in this study we describe the interactions between children/adolescents and botos in markets/fairs in the towns of Mocajuba (lower Tocantins River) and Santarém (lower Tapajós River), in Pará State, Brazil, focusing on the context that those interactions occur and the most frequent behaviors observed in the process. 4 2. Methods 2.1 Study area We conducted our research in markets/fairs of two localities in Eastern Amazon, both located in Pará State, northern Brazil (Figure 1). One of these places is the town of Mocajuba (2°35’31”S, 49°28’60”W) in the lower reaches of the Tocantins River. The other market/fair is located in the city of Santarém (02°25’30”S e 54°42'50”W) in the lower Tapajós River at the confluence with the Amazon River. Both the Tocantins and Tapajós are clearwater rivers with intermediate fertility (Junk et al. 2011). The lifestyle of human populations working or depending on the markets we studied share some common Amazonian characteristics as the consumption and commerce of products originated from the forests and rivers, such as fruits, fish and herbs. Even though the city of Santarém has a larger population and is more urbanized than Mocajuba, the market located on the margins of the Tapajós River still retains traits that connect city, countryside and nature (Lefebvre, 2001, p. 68).

Some reports and articles, however, mention the occurrence of botos within the rapids region and that they occasionally cross the rapids, but without mentioning the species concerned. Based on our previous studies, it is likely that I. boliviensis occurs in the region of the rapids. To test this supposition, we sampled 18 individuals from this region, and collected mitochondrial (control region, cytochrome b and cytochrome oxidase I) and nuclear (10 microsatellite loci) DNA data, in order to test if there is connectivity between the dolphins that were found within the rapids region and dolphins collected upstream and downstream of the rapids, and investigate population structuring between these localities.

Armbruster2 Introduction of fish species is a globally widespread practice that causes losses of native species and homogenization of diversity within and across continents. Diet assessments are important tools to depict the ecological function of species introduced into novel ecosystem and possible direct and indirect ecological effects. In this study, we compare the diet of Piaractus brachypomus, a mainly frugivorous Neotropical fish, introduced into the Sepik-Ramu River Basin (Papua New Guinea) nearly two decades ago, to that of similar size individuals from Neotropical populations in the Amazon and Orinoco River basins (South America). In contrast to native populations that feed mainly on terrestrial plants and invertebrates, the diet of introduced P. brachypomus is mainly composed of fish remains and aquatic plants, while terrestrial plants are frequently consumed but in relatively smaller amounts. These findings show that P. brachypomus has an inherently plastic diet that can be adjusted when displaced to a novel geographic area. While trophic plasticity increases the likelihood of a species to establish breeding populations after its introduction, it also reduces our ability to predict negative effects on native species. La introducción de peces es una práctica que se extiende globalmente y que causa perdida de especies nativas y homogenización de la diversidad dentro y entre continentes.

  • An Assessment of Exotic Species in the Tonle Sap Biosphere Reserve
    AN ASSESSMENT OF EXOTIC SPECIES IN THE TONLE SAP BIOSPHERE RESERVE AND ASSOCIATED THREATS TO BIODIVERSITY A RESOURCE DOCUMENT FOR THE MANAGEMENT OF INVASIVE ALIEN SPECIES December 2006 Robert van Zalinge (compiler) This publication is a technical output of the UNDP/GEF-funded Tonle Sap Conservation Project Executive Summary Introduction This report is mainly a literature review. It attempts to put together all the available information from recent biological surveys, and environmental and resource use studies in the Tonle Sap Biosphere Reserve (TSBR) in order to assess the status of exotic species and report any information on their abundance, distribution and impact. For those exotic species found in the TSBR, it is examined whether they can be termed as being an invasive alien species (IAS). IAS are exotic species that pose a threat to native ecosystems, economies and/or human health. It is widely believed that IAS are the second most significant threat to biodiversity worldwide, following habitat destruction. In recognition of the threat posed by IAS the Convention on Biological Diversity puts forward the following strategy to all parties in Article 8h: “each contracting party shall as far as possible and as appropriate: prevent the introduction of, control, or eradicate those alien species which threaten ecosystems, habitats or species”. The National Assembly of Cambodia ratified the Convention on Biological Diversity in 1995. After reviewing the status of exotic species in the Tonle Sap from the literature, as well as the results from a survey based on questionnaires distributed among local communities, the main issues are discussed, possible strategies to combat the spread of alien species that are potentially invasive are examined, and recommendations are made to facilitate the implementation of a strategy towards reducing the impact of these species on the TSBR ecosystem.

  • Phylogeny of All Major Groups of Cetaceans Based on DNA Sequences from Three Mitochondrial Genes
    Phylogeny of All Major Groups of Cetaceans Based on DNA Sequences from Three Mitochondrial Genes Michel C. Milinkovitch,* Axe1 Meyer) and Jeffrey R. Powell * *Department of Biology, Yale University and +Department of Ecology and Evolution, State University of New York at Stony Brook Traditionally, living cetaceans (order Cetacea) are classified into two highly distinct suborders: the echolocating toothed whales, Odontoceti, and the filter-feeding baleen whales, Mysticeti. A molecular phylogeny based on 1,352 base pairs of two mitochondrial ribosomal gene segments and the mitochondrial cytochrome b gene for all major groups of cetaceans contradicts this long-accepted taxonomic subdivision. One group of toothed whales, the sperm whales, is more closely related to the morphologically highly divergent baleen whales than to other odontocetes. This finding suggests that the suborder Odontoceti constitutes an unnatural grouping and challenges the conventional scenario of a long, independent evolutionary history of odontocetes and mysticetes. The superfamily Delphinoidea (dolphins, porpoises, and white whales) appears to be monophyletic; the Amazon River dolphin, Inia geofiensis, is its sister species. This river dolphin is genetically more divergent from the morphologically similar marine dolphins than the sperm whales are from the morphologically dissimilar baleen whales. The phylogenetic relationships among the three families of Delphinoidea remain uncertain, and we suggest that the two cladogenetic events that generated these three clades occurred within a very short period of time. Among the baleen whales, the bowhead is basal, and the gray whale is the sister species to the rorquals (family Balaenopteridae). The phylogenetic position of beaked whales (Ziphioidea) remains weakly supported by molecular data.

  • Catfish Fisheries Pose Threat to Amazon River Dolphins
    Water Education Catfish Fisheries Pose Threat to Amazon River Dolphins Vanessa J. Mintzer The Enchanted Boto n the expansive rivers, floodplains, channels, and lakes of the Amazon Ibasin, swims an aquatic mammal unlike any other, a creature renowned through the region for its unique ecological and cultural roles. Having spent 30 million years in the Amazon, the Amazon River dolphin (Inia geoffrensis), also known as “boto,” has evolved multiple morphological characteristics that set it apart from its marine counterparts. With an unfused vertebra that allows its neck to bend at a 90-degree angle, an elongated snout that facilitates foraging in submerged tree branches, and molars that crush riverine turtles and crabs, the boto is a highly efficient predator in Amazonian aquatic habitats (Figure 1). Even the seasonally flooded forests of the basin provide suitable habitat for this robust but flexible animal, which can easily maneuver its way between trees in search of prey (Figure 2). In addition to its ecological importance as a top predator in the Amazon aquatic ecosystem, the boto is a focal figure in Amazonian culture. For generations, stories of the shapeshifter boto, or encantado, have been told readily throughout the region. Although the stories are diverse, many describe that the boto can take human-form at night, attend parties, and seduce persons of the opposite sex. One of these legends, rich in detail, explains that the boto turns into a Caucasian man, dressed in a white suit and matching white top hat (that hides the dolphin blow-hole still present on the man’s head).
